.This invention relates to improvements window channel, sucli as Ausedjfor the Yreception and guidance of the slijdable WIldOW panes ofvehicle bodies and thejlike.

The 'invention has more particular relation to the covering or (liningofsuch `a channel, the invention having iforits y.primary object thepro-` vision of a `channelhaving@simple and improved covering or liningf or the `core thereof,`sad covering or'liningbeing of inexpensiveforrnand adapted for application `to said core atlow cost.

A more speciiic object of 'the present 'invention is the provision of vachannel 'having Va `core covering or lining. Whchjincludes suitablyspaced rows of Woolen threads, lainents or cords for contact WiththeWindow pane which thepchannel receives and guides in use thereof, saidwoolen threads, laments or cords 'being carried by inexpensive .sheetmaterialso that the cost of the covering orlining is quite low.

Further objects ofthe present invention, and many of its practicaladvantages, will be referred'to in or will'be evident from the followingdescription thereof, reference being. had `to the accompanying drawings,.in which `Fig. 1 represents in cross section and in perspectiveonelform of window channel Vembodying the present'inventon;

Fig. `2 is a similar view of the channel covering or lining laid out in`flat or developedform;

Fig. 434 is a longitudinal sectional elevation through one -of 'the ribsof the covering or lining;

Fig. l 'is a similar View showing aslight modification; and

Fig. 5 is a similar view showing yet another modication. l

Before the invention 'here involved is specifi# cally described, itis tobe understood that itjs not limited lto 'the specific details ofconstrue.- tion and/or the specific arrangement of parts hereinillustrated ordescribed as theinventon obviously mayjtake various forms.'It also is to be understood that the-phraseo1ogy or termi; nology=herein demployed is for Vpurposes of description and `not ofilimitationgthe scope of the invention'being denoted bythe appendedclaims.4

`For clarity and Vsimplicity of illustration, all views'of the drawingsshowthewindow channel or'its parts considerablyfenlargedand somewhatexaggerated. #The channel shown includes acore of any suitable material,such als sheet metal, and bent to provide aibase l'ID-'and ay pair of`generally parallel "side walls 1H, -the `outer or lfree longitudinaledges fof 4vvliicli are 'here rolled around1reeenfo'rcingfwires ft2. i

The covering" ,or ,lining VforV said A.Golfe .comprises a layer I4 ,of.any v.Suitable sheet` material, fs'uch as cheap cotton fabric, ,forexample, .the layer being here shown .as of sufficient width Vto com.-pletly enclose `or envelop the channel c ore and the longitudinal edges.of said ,layer 4,being here shown .as .meeting along .the lower surfaceoffthe core ybase Ill,f as` at 1.5.., Within the channelcore, the layerI4 is provided -with .suitably located longitudinally extending .rows ofwoolen material for ContactwithA the window A.pa-rie. 4which Athechannelreceivesand guides in use thereof. Bref.- erably and as Ahereshown, fthe Lwoolen material is in the form of threads., `filaments. orcords, ar,- ranged in successive stitches of any suitable type. l

`In .the embodiments .of `-the invention here illustrated, lltherelareftwo side rows i6 :ofV such woolen stitches, for contact with .thevlateral faces ofthe wifrlddwpane,,andabottom row ,I1 of such Woolenstitches, 14for contact .with the edge of thewindowpane, although said,bottom rowmay be omitted, if desired.

Tol locate the rows oi Woolen stitches on the crests of inwardlyextending, longitudinally disposed nbs olr jtheiikje, Ifor `ijnorie veffective Contact with the window pane, the covering or .lining layer,IA Avhas ,here .associated therewith, in the lngtlidialpne ,of eaCh ofits rows of stitches, a Arope-like V elemelfit 4`[8L These ,ribeformirlgelements l8 underlie' ,thejlfyer '|'4 and may be and preferablylaresecured to suchglayerjby the rows of woolen stitches. Any suitablematerial ,may be utilized forti-1e formation of the rope-like elementsVi8, such as cotton roving or v.padding or even paper or ,paper-likematerial, `in some twisted form, ufor example, may be used, if de-`sired.

If desired and as here shown, lthe core cover- Ving vor lining Vmay alsovinclude *a base vlayer 20 of any suitable sheet material, 4such falscheap cotton ifabric orthe 1like, with the consequent disposition of'the rib-forming elements 18 -be tween the ftwo 7layers, as shown.Although the baseilayer 2U may havelany desiredwidt-h, -it is herefshovvn as being of rsuch v:width V'as to enable its longitudinal edgesto Icoincide with Vthose -f the-outer'layer ff4`when-the' two layers areintheir superposed relation, r a-relationship -which can be-maintainediby the use of? any-suitableA means.

`inthe4 embodimentjof ythe invention illustrated in Fig-s. l1 toSfinclusive, the relatively'iheavy wolen threads l'I'li and '|71passthrough'the ,outer threads are relatively light threads 2| (thebobbln threads of the stitching operation) which pass through the baselayer 20 of the covering material and into the rib-forming elements I8for single lock stitch connection with the woolen threads I6 and I1. Inthe embodiment of the invention illustrated in Fig. 4, the woolenthreads (a single side thread Ilia being shown) pass through both layersIda and 20a of the covering material and through the rib-.formingelements I8@ therebetween. In this formof the invention therefore, thebobbin thread 2Ia lies below the base layer 20a of the covering materialwith a double lock stitch connection with the woolen threads, althoughsuch stitching, in both these embodiments of the present invention, issuiiicient to maintain in assembled relation the several parts of thecore covering or lining, additional means may be and preferably is usedto maintain in contacting relationship those portions of the twocovering layers which lie on opposite sides of each rib-forming element,such as an adhesive or other equivalent means.

The woolen stitches here utilized may be of any suitable form, butpreferably are of such nature as to present to the window pane, wherethey are exposed on the crest of each of the inwardly extending ribs orprojections of the cover ing or lining, a series of closely spaced,longitudinally extending portions of fairly large diameter. In each ofthe present embodiments of the invention, the woolen threads, filamentsor cords constitute the needle thread of a machine lock stitch, thebobbin thread thereof being a much smaller thread, as shown.

In Fig. 5, a single lock stitch is again shown, but in this form, thewoolen needle thread |61) merely passes through the outer layer Illb,its locking thread 2Ib being thus disposed directly therebelow. For theconnection to each other of the two layers I lib and 20h of thiscovering or lining, and for the maintenance therebetween, in properlyspaced relation, of therib-forming elements I8b, any suitable means maybe utilized, such as an adhesive, other stitching or the like.

In all embodiments, of course, the covering or lining is suitablysecured to the channel core, such as by an adhesive, as is usual.

Fromthe foregoing description of the invention here involved, it will beevident that the core covering or lining of the present channel is ofsimple and inexpensive form, as but little woolen material is requiredfor the rows of stitches which contact the Window pane. To those skilledin the art to which the present invention relates, other features andadvantages of such invention will be evident from the foregoingdescription of several embodiments thereof.
